We're all excited for the science fiction future reality of Google's 'Project Glass' but without actually trying them on, we have no idea how they'll actually work. Let's just hope they don't work like this hilarious parody of Google's demo video where people run into poles and fall to the ground because they're so distracted.

Made by Tom Scott, the video shows how the Google Glasses will make you run into people because you've been bombarded with ads. It's hilarious. [Tom Scott]
